Please change the possibility to use IRs only on one Output, so we can use a Guitarspeaker with Amp on the other Output. That Possibility is on Ampero Stomp and others already build in. Also would it be fine to change the Modulationeffekt in Future.

we already have that as a feature request

> The main use case for the NC (for me) would be a backup for my QC, which I currently have set up to send a pre-IR signal out of one output and a post-IR signal from the others. If the NC could be set to send the Post-IR signal from one output, and a Pre-IR signal from the other, this would serve as a great backup unit for those using IRs with a real cab on stage. This would (ideally) just be a configuration option that would apply to all presets and is switchable from a main menu.
